The sale of a business is a complex process that requires careful document management. With the advent of electronic signatures, this procedure can be simplified while maintaining its legal validity.
Applicable Legal Framework
eIDAS Regulation and GDPR
The European eIDAS regulation (Regulation 910/2014) defines the criteria for recognizing electronic signatures. Article 25 specifies that an electronic signature is valid if it meets the conditions for authentication, preservation, and non-repudiation. The GDPR (Regulation 2016/679) applies to the processing of personal data related to this transaction.
Document Retention Periods
According to Commercial Code L123-22, books and records must be retained for ten years. Tax supporting documents are retained for six years under the General Tax Code L102B. For social security contributions, the retention period is three years in accordance with the Social Security Code L243-16. Finally, for payroll documents, it is five years under the Labor Code L3243-4.
Business Sale Procedure
